Monsterbating

When you jerk off so hard that its scary but it feels so good that you wanna squirt EVERYWHERE!

To being jerked off really hard and vigorously.

Honey! Why are you jerking off so hardddd!

Oh don't worry honey, I'm only monsterbating it doesn't hurt.

When a person rubs his girlfriends pussy and uses the juices to jerk off.

Babe, I can I get some? Sure honey.....I'm not hard yet so let me get some of that hand gravy to jerk off with!
